Proper publishing setup (#17)

* Attempt at fixing published artifact

* wohoo it works

* attempt at excluding bootstrap's shadow jar from publishing

* Update gradle, fix publishing (aka, dont publish shadowed bootstrap build to maven)

* Don't apply shadow plugin for the converter

* why are we publishing the lib as an artifact...?

* make these implementation

* Shade bedrock-pack-schema into pack-schema-api
